Unreleased DOS conversion of Team 17 1993 Amiga games Overdrive. This conversion was developed, in 1993, by Holografix team from Italy (Francesco Iorio, Matteo Tesser and Giulio Fornasar) but was never released.
Compared to the official DOS conversion, published in 1995, the one by Holografix features four opponents on the track (instead of two in the original version), MIDI music and was designed to run at 60 FPS on a 386SX with standard VGA. This version is complete, but the difficulty is still a bit unbalanced and there are a few bugs.
All graphics in the game are by Team 17.
